For the people who have removed there plenums did you replace all the o ring or did you re-use them, also do the inlet manifold gaskets need replacing and is sealant needed when replacing the chamber, i need to take my injectors out to get cleaned so thats why im asking,
the o rings are reusable, i've pulled the plenum off several times and i havent had a drama. just make sure u inspect the orings for damage. if they look fine not brittle or marked, they should be sweet as far as the manifold gaskets, u mean between the head and manifold? im not too sure, but i would get another gasket just for safety measures. dont know about the sealant, if u need to use it or not.
